CASH-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 523,611, dated July 24, 1894.

Application filed August 28, 1893.

To aZZ whom, it may concern.-

Be it known that I, JEROME J. WEBSTER, a citizen ofthe United States, residing at Northampton, in the county of Hampden and Stateof Massachusetts, have invented new and useful Improvements in Cash-Registering Machines, of which the following is a specification.

This invention for improvements in cash registering machines relates to improvements in the key operated register devices and improved means for acting in conjunction therewith for preventing what is termed pumping of the keys; that is for preventing while the key is being depressed an intermediate movement in the return direction, or while the key is returning an intermediate movement for the depression thereof;

in a variety of ways in cash registering machines, but the object of this invention so far as it relates to this device is to dispense with the series of ratcheted wings on the key levers and the long or common locking pawl for engaging the key levers as well as the somewhat complicated arrangement of operating devices for the long pawl.

The invention also relates toimprovements in the means for operating the cash registering mechanism in varying extents according to which of the keys may be operated.

The invention also relates to improvements in the registering mechanism, the improvements more particularly residing in the mechanism for insuring the transfer of amounts from the initial register wheel onto the accumulators or adding wheels;an important feature of the transfer devices being constituted by the novel means which prevents over registration, as might be ensured by momentum due to violence of operation of the initial register.

In the accompanying drawings the present improvements are illustrated.

Figure l is a side elevation of the cash registering mechanism as removed from the cabinet or casing. Fig. 2 is in substance a front vertical cross section taken on line 2,- 2, Fig. 1. Fig. 3 is a perspective view taken at the front of the machine showing more clearly Serial No. 484,257. (No model.)

the novel devices. Fig. 4 is an end elevation of the transfer device a part of the initial wheel being shown in vertical section, while Fig. 5 is a plan view of the same.

In the drawings A represents the initial registering and dial wheel having, forinstance as shown in Fig. 2, a consecutive series of indications of amounts in multiples of five cents up to one dollar, the dollar capacity being five fold or five times repeated around the face of this single wheel. This wheel has on its shaft or arbor, at the rear thereof the ratchet wheel A with the properly spaced teeth to correspond with the five cent graduations or indications on the dial wheel. To all intents and purposes the dial wheel and the ratcheted wheel are one, or as an integrally formed element. The ratchet wheel has the pins a a at fifths to correspond with the dollar amounts on the register wheel.

The key levers may represent amounts say from five cents to fifty cents, these keys operating to impart a reciprocatory movement to the plate B which carries the driving pawl b for the register wheel, in correspondingly varying extents. Thisis insured by the grad ing of the cam slots or cam inclines seen at 0c 00. The rear extensions of the key-levers y work against these inclines to force the plate to the right so that the pawl will have a retracting and clicking movement over the proper number of the ratchet teeth of the initial register wheel to next positively drive the wheel forward the proper distance as the plate has its return and working movement to its limit, as impelled by its driving spring 0.

G represents the rocker plate which is common to and is moved by any one of the key levers of the bank (except the change or nonregistering key, when such a key is usedas well known).

The graded cam plate B has on its upper edge a series of fine ratchet teeth f with the vertical or engagement faces thereof toward the right, while adjacent this ratcheted edge of the plate a pawl d, is, intermediately thereof, pivotally hung upon a suitable stationary suptnted by the Hat strip of thin metal set and secured in a saw kerf in the body and pro jected longitudinally from the end thereof. The pawl is held normally out of engagement with the ratchet teeth and only engages the same after the plate B has been moved to the right such distance as insured by any of the fully depressed keys,-the engagement coutinuing until the plate has returned to its normal position by the force of its spring 0, correspondingly driving the register wheel. This return movement of the said plate is in this mechanism the working movement.

The means for holding the pawl out of the engagement as stated will be now pointed outz- A lever g is hung on a suitable arm or support a of the framing, the extremity of which enters a hole in the body of the awl d at the side of the pivot opposite the pawl tooth; thus when the lever is swung the pawl is pivotally swung also into engagement with the ratchet teeth, f. The lever is swung just at the completion of the depression of the key-lever, and consequently of the rightward movement of the plate B, by the arm, h, which v is a rearward extension of the rocker plate and which is arranged to contact with and swing the lever at just the instant stated. The lever is retained in its so swung position for the proper period during the operation of the mechanism by the catch lever 2' depending from its supporting pivot i and having the catch shoulder i to take under the lower edge of the swung pawl-operating-lever, g. This catch lever swings by gravity or spring i into its engaging position, and its engagement with the lever is terminated just as the pawl carrying plate 3 reaches its normal position by the abutment of the properly positioned st-udj, against the catch lever to swing it to the left, whereupon the lever down-swinging by its weight also swings the pawl (Z out of engagement with the ratcheted upper edge of plate 13.

Now it will be plain that while the key after being depressed is returning to its original position, and the graded cam plate and pawl are driving the register wheel forward the key can not be given any intermediate move ment of depression to take a supplemental hitch, to falsely register, as well understood, on the register wheel, because the key cannot be depressed without moving the plate 13 to the right, and the plate is by the pawl cl never permitted to be moved to the right between the times that the key is fully depressed and the plate 13 and key resume together, their original positions.

Now will be described the improved means for necessarily rendering the depression of the key and the rightward movement of the plateB continuous--no intermediate leftward movement being permitted as would also result in false registration.

G represents a dog or pawl constituted by a block or plate which is slotted obliquely as at and, by the headed screw 73, has a sliding engagement in an oblique direction on the framing and at its edge toward the ratcheted register wheel; this dog has the tooth, Z, which at times may engage the said wheel to lock it against movement. The spring, Z is applied to draw the pawl into its engagement by its tooth with the ratcheted wheel. The lower portion of the pawl is of bifurcated formation the member 12 being extended to contact with the right hand member of the pawl d, while the other member 13 has its edge curved or inclined and moves in contact wit-h, and the pawl is, therefore, swung by, the fixed stud, 14. Briefly, the pawl G is in engagement with the register wheel whenever the pawl 65 is out of engagement with the ratchet teeth of the plate B, and vice versa. The swinging of the pawl (Z to its engagement forces through the limb 12 of the pawl G the said latter pawl out of engagement, while on the other hand when the pawl (Z moves into its position of engagement it gives room to the pawl G to move under the impetus of its spring. As this pawl therefore has its somewhat slight sliding movement by its slot over the screw bit also has a slight swinging movement for more directly and quickly bringing the tooth Z into the register-wheelengagement by reason of the coaction of the stud 1 1 with the inclined limb 13 of the said pawl.

Other designs of the parts might perhaps be made whereby the swinging movement of the pawl G, in addition to its sliding move ment, might not be necessary, but in the mechanism, illustration of which is here given, the entire freedom of the pawl from the ratcheted register wheel at the one time, and its absolute and certain engagement thereof at the other are the better insured on a slight throw of the parts by imparting to the pawl G both the sliding and the swinging movements.

The transfer and accumulating or total adding wheels are shown at ll the first to the right for instance registering units of dollars as transferred thereunto by the initial registering wheel, A, while the nest succeeding wheels to the left are for indicating tens, hun drcds and thousands of dollars their indica tions being peripherally arranged in a common manner. l lo detailed description of this registering mechanism isherein necessary or desirable except with respect to the units of dollars wheel which is the one, m, to the right. This wheel has on the end ofits shaft or arbor a ten-toothed wheel m here shown in the form of a ratchet wheel,--although such form is not absolutely essential,--a teeth of which is engaged by each of the passing pins A of register ratchet wheel A in a manner to carry the ratchet wheel m and wheel m around one tooth or step. The wheel m also has as are therewith the toothed wheel it also with ten teeth. The angular lcvero is, at its elbow, pivotally mounted on a stationary support and has its one arm 0 extended into proximity with the teeth of ratchet wheel m while its other arm 0 has the right-angularly extended member 0 which has its position near the said toothed wheel n. The slabbed pins 01' studs a of the wheel A are at their ends as seen in Fig. 5 so wide and so arranged as to simultaneously engage both a tooth of the ratchet wheel m and the arm 0 of the angular lever so that before the pin a slips by or free from the tooth of the ratchet wheel m it will have swung the angular lever so as to bring its member 0 into a position to intercept the next tooth of the wheel n which is now to the rear of said member 0 The spring p is applied relative to the member 0 of the angular lever to force said lever to resume its normal position of disengagement from. the toothed wheel n immediately the stud a has passed out of its engagement with the arm 0 This device therefore while not interfering with the movement of the register wheel to to the extent of one tooth or step, as positively and properly driven by the successively passing pins Ct will prevent, on a too violent impulse, the driving forward of the wheel m more than one tooth or step, by momentum, to result in an over-registration.
